ROOF STRUCTURE.

Application filed October 9, 1926. Serial No. 140,646.

The object of the invention is to provide an improved thatched shingle roof structure.

Objects relating to details and economies of construction and operation of my invention will definitely appear from the detailed description to follow.

The invention is defined and pointed out in the claims. 4

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. 1 is a detail perspective view of the end of a thatch shingle roof'of my improved structure.

Fig. 2 is an enlarged detail sectional view on line 22 of Fig. 1, showing the method of laying the roof and the method of lapping it around a curved thatch cornice.

Fig. 3 is an enlarged detail perspective view showing the roof in process of being laid.

Fig. 4 is a plan of a roll of flexible asphaltic roofing material showing how the shingles are cut from a roll without waste.

The parts will be identified by their numerals of reference which are the same in all the views.

1 is my improved roof made up of m improved shingles. 2 are the roo -boar s extended into a curved cornice at 3. 4 are the shingles cut crosswise of the usual roll of flexible material as seen in Fig. 4.

The shingles are in practice five inches long for ordinary use and as wide as the width of the roll. The shingles are of curved contour and made up of symmetrical forms each side of the center line, forming a broad concavoconvex curve at the middle and reverse curves of half the length at each side. Each half of the shingle is thus made up of oppositely recurved 8 portions which are each symmetrical to the other half. The shingles can thus be joined on the roof either end to and fit. perfectly together.

The shingles are laid in straight horizontal lines on the body of the roof twoinches to the weather. The shingles are laid by preferably dividing the roof by chalk lines two inches apart by which the shingles are laid. They are offset and break joints at irregular intervals. Further at intervals a shingle can be reversed to have its center curve upwardly instead of downwardly. By this irregular shifting and breaking of joints an irregular lapping of the shingle is secured over the entire roof and at the same time a two-inch lap is maintained.

The end shingles of each row will have a straight edge. These are made use of at top and bottom and asuflicient number of the shingles are purposely formed that way to take care of the eaves edge and the ridge of the roof.

By making the shingles of the same contour they can be made very rapidly and without waste of material.

I have shown a preferred width and length. The size can be varied and double length shingles might be made by connecting two together and secure this result. This method lends itself particularly well to variegated colors of shingles as the small irregular projections secure a very fine blend of the colors without any patchy effect.

I mention these modifications as I desire to claim the invention broadly and also specifically as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A roof made up of broad shingles at least twice as long as they are wide with identical curved edges at top and bottom forming a broad central conca-vo-convex curve and reverse end curves, the same being overlapped and a portion reversed and breaking joints at irregular intervals on the roof, as specified.

2. A roof, the body of which is made up of strip shingles at least twice as long as they are wide with curved corresponding contours at top and bottom forming concavo-convex curves at the middle and reverse curves of half the length at each side laid in ofi'set relation to produce an irregular effect in the lap of the shingles, as specified.

In witness whereof I have hereunto set my hand. I
